# coroutines

[elizarov]

You can always fine-tune your performance later. You have at least two tuning means -- using Unconfined dispatcher for very light-weight coroutines (they will always execute in somebody else's thread without any thread switch/dispatch) and using CoroutineStart.UNDISPATCHED to run initial portion of the freshly started coroutine directly in the invoker thread.
